Status of US EPA program to validate the HILS methodology and resolve error codes.

Presentation on the scope and content of US EPA activities with regard to vehicle emissions (including heavy-duty, non-road, and light vehicles).

The current draft GTR on motorcycle evaporative emissions includes seven options for the test fuel; however, the list does not include the fuel specified under US and Canadian requirements. Therefore, the US and Canada request the addition of a new option corresponding to the fuel specifications laid out in the United States Code of Federal Regulations, Title 40, Part 1051, section 501 (40 CFR 1051.501).
